Sound Quality:-
The BT transfer equipped with a hybrid setup delivers satisfying level of clarity and details. For a BT device it manages to delivers good amount treble extension and energy. It has a well balanced sound with a bit more emphasis on mid range. I find the tonality very accurate and the timber very natural for the price. The sound signature is a bit coloured with a warm and darkish feel.
Burned for more than 60hrs I have used my Samsung M30s and Shanling M5s for this review.
Bass:-
Powered by the 9mm dynamic driver the lower end is voluminous and meaty. The sub bass has good extension with nice rumble and movement of air to it. The mid bass is a bit healthier than the sub bass region. It is nicely rounded with a nice slam to it. Notes feel fuller and full bodied. There is good amount of texture to the notes. The decay speed is slightly on the slower side making things boomier and a bit wooly. Upper bass has nice control over notes. Good thing is the BT transfer doesn’t try to restrict the notes and let them express themselves.
Quantity wise it lies some where in between the Form 1.1 amd DUNU DM480. Quality wise it is slightly inferior to both the wired IEMs but is very close to the Form 1.1 and is better than Revonext QT2s.
Mid range:-
Even when the setup is hybrid the BT transfer’s mid range doesn’t lack with energy or forwardness. There is no crossover mentioned anywhere so it is difficult to say which driver is responsible for the mid range. Nevertheless the transition region of upper bass to lower mid feels well forward and transparent. There is bit of veiling in the region though. Vocals sound pleasing with very accurate tonality. Both male and female vocals have pleasing notes sharpness and good amount of texture. Male vocals have a nice throaty feel to them. Instruments have good clarity and details to them and are comparable to wired earphones in the price range of $50. A bit of micro details is polished and that can be forgiven because it is a crime to expect wireless devices to pickup fine details.
The stage is big and aptly spacious. Instruments have good amount of space between them. There is good amount of width and height but the depth is slightly lacking. Layering and separation is very good for a wireless IEM.
Highs:-
The upper end of the BT Transfer is considerably better than what I have seen with a handful of earphones and headphones using BT4.2 (EG. Brainwavz BT300). The BT5.0 definitely brings improvements to this region of the spectrum. Even when I use Revonext QT2s with TRN cable the Treble is not as extended or lively as the BT Transfer.
The treble region has good amount of energy and spark to it. It is not the liveliest but is more energetic than Form 1.1. I find the treble to be slightly spiky at the lower treble region. Notes can be a bit sharper then they need to, giving a perception of better detail. Micro details are slightly missing though. Treble extension is average when compared to wired earphones but is more than enough when compared to wireless earphones. Layering and separation is good, there is okay amount of air between instruments. The treble stage size is big enough to not to make it clumsy.
For a wireless earphone, I am impressed.
COMPARISONS:-
VS Signature Acoustics Ocean (with SA BlueLink 2pin BT5.0 cable) ($70):-
This one houses 2 dynamic drivers and one BA driver and is an OEM form BQEYZ. The best things about this combination are the level of micro details, clarity across the spectrum and battery life.
The bass is slightly less boomy and sounds more resolved with better details. The slam size or air is better with the BT Transfer. Mid range of the Ocean is less forward and slightly reserved with a metallic tonality. It does churns out better micro details where the BT Transfer sounds slightly less transparent and a bit blunt with notes sharpness. Treble region is where the BT Transfer struggles a bit against the SA Ocean and blueLink. The Ocean has better treble extension and energy. Stage size of the Ocean is more rounded where as the BT Transfer has a wider and taller but a shallower stage.
Connectivity of both the earphones is fantastic without much trouble unless the source is behind a metal sheet or wall or obstructed by bones. The range is very similar too. The buttons on the BT Transfer are more supple and soft to the hand.
Build quality of both the earphones is fantastic. With wire type cables both are easy to carry inside the pocket.
VS Brainwavz BLU300 ($30):-
The BT4.2 powered single dynamic driver IEM struggle a lot to keep up with the BT Transfer.
The bass is similar with slam size and air but has slightly slower decay and boomier mid bass. There lesser amount of details and texture. The mid range has lesser transparency and clarity with notes lacking depth and bite. Treble has considerably less extension and doesn’t have much energy. Stage size is acceptable but is smaller than the BT Transfer from every direction.
Connectivity wise the BT Transfer is much more superior while having lesser dropped frames and lag. Range of the BLU300 is similar though. Build quality of both the earphones is fantastic but I find the neck band of the BLU300 to be less portable. You cannot put it in a case and carry it in your pocket.
Conclusion:-
The biggest problem with the TWS earphones is the fear of losing them, if not both, one side. You might not be able to save the IEM if it falls out of your ear onto the gravel or marble floor. The next best thing is IEM with a supple cable which can be carried inside the pocket and that is what the BT Transfer is providing. Better security without missing out on quality and clarity.
The fit-wings do their job perfectly. The whole package feels very elegant and the battery life makes it a pure winner. You don’t have to worry about charging it twice a day, it easily lasts a day of work and play.
I totally recommend the BT Transfer if you are after an IEM for your Mobile phone which doesn’t have 3.5mm option.
